To all whom it may concern:

Be it known that I, Mlcnzinn J. Ksnos, citizen of the United States of America, and a re ident of Fort e of Indiana, have invented certain new and useful 1mm .cuieuts in. Electrical Switches, of which the following lS a spccification.

"This invention relates to improvements in electrical switches, especially for use in connection with the a further object being to afford means for opening over head circuits at points unprotected from the weather.

The atmospheric variations and conditions to which this invention is intended to be subjected in use are at times extremely violent, and it will be understood that the construction herein set forth has been especially devised to overcome difliculties due to opposing Weather conditions.

The above objects are accomplished by the construe tion illustrated in the accompanying drawings, in which:

Figure 1.15 a section oi the apparatus on the line 9;z of Fig. 2; Fig. 2. is a transverse section oi he same on the line y--y of Fig. 1; Fig is an end el- .ion of the apparatus; Fig. is a detail view oi one oi the. insulating supports for the contact; terminals; Fig. 5. is a do tail showing a sectional view of one of the bell-mouthed receivers; and Fig. (i. is a similar view of the flexible end of one ol' the CUHLSLU'L-LG1.U1ll1E1l-S.

Similar numerals of reference indicate corresponding parts throughout the several views, and referring now to the same: ll are vertical supporting posts, and 22 are horizontal beams secured to said posts. The posts are arranged in opposite pairs. and the beams 2 are arranged .thereon oppositely in parallel relation with each other. Cross arms 3 are rigidly secured upon the uppermost beams 2 and afford fixed support for the receiving contact terminals 4.

A movable frame 5 is pivotally supported at the upper ends of parallel swinging arms '6, the latter being arranged in opposite pairs and each of said arms has at its lower end a pivotal connection (as shown at '7) with the corresponding beam 2. The frame 5 has mounted thereon a series of contact terminals 8 which are adapted to connect with the corresponding receiving terminals 4 when the frame is in closed position.

'lheconnoctions oi the receiving teriiuiuals with the cross-arms 3 and the connections ot' the contact-termirials 8 with the frame 5 are made with insulators 9 of 1 great elliciency. Each of said insulators has fixed upon'. its top on anchor-block 10 in which is fixed the corresponding terminals 4 or 8, thus the said terminals are held in rigid relation or from. the Lu J Each 0 the terminals has areceiving' socket 1]. and a hell. shaped mouth 12 at one of its ends, and the'adjacent end of the corresponding contac -hrminal 8 has fixed thereon. a flexible connecting plug 13 which is adapted to enter the socket 11 and form an electrical 55 connection with the corresponding receiving terminal 4. The receiving-termii .s d are connected with the correspomliug ends 14 or the linswires by means of suitable conductors l5, and the coutactterminals 8 have respective connections with the corresponding oppo site ends 16 of the line wires by means of flexible conductors 17. The ends Mend 16 of the line Wires are anchor-0'11 respectively to insulators 19 which are mounted upon corresponding cross-arms 20, the latterbeiug supported by the posts 1. Battle plates 21 are mounted upon the cross-arms 3 and range in vertical planes intervening between the respective pairs of contact-terminals.

In the operation of this invention, the frame 5.-is swung upon the arms 5 by applying mechanical force to said frame or arms so that the contact-terminals 8 will be carried forward. and form connections with the corresponding receiving terminals 4, thus completing electrical connections between the opposite ends 14 and. 16 oi the corresponding line wires. While the appaint-us is in this position electrical currents will be conducted without obstruction from one end of each line wire to the corres 'iondingopposite end thereof. When it is desired to break the electrical currents, the frame 5 is swung outward so as to carry the contact-ter- 9i) urinals S from connection withthe receiving terminals l, thus opening each of the conducting circuits simultaneous At the instant of separation between the respective terminals 8 and 4, electrical arcs will form and become extended until the distance between the parting terminals become sufliciently great as will afford such resistance tobreak'the currents. The pivots 7 are so arranged in relative positionto the frame 5 that when the latter is moved to open position it will sition, thus moving the Contact terminals 8 oppositely to the upward tendency of the, arcs and thereby affordiug further resistance to their maintenance than would be if the terminals were moved in a' horizontal plane of the arcs is occasioned by attending heat. 7

Having described my invention What I claim as new and desire to secure by Letters Patent, is:

1. In apparatus or the class described, supporting posts be carried to a lower plane than when in its closed poonly, it being understood that the upward tendency arranged in opposite pairs, each pair having hoiiaonta'l llil np 'iermnsl, beam 01' each pair of new;
